The development of construction waste processing production line is imperative

With the accelerating urbanization, one high-rise building has risen, which not only consumes a lot of resources, but also generates a large amount of construction waste. According to incomplete statistics, Beijing produces about 40 million tons of construction waste every year, involving construction waste crusher, municipal road projects, landscaping projects and various maintenance and demolition projects. There is a staggering amount of construction waste produced in Beijing alone, not to mention the whole country. In the face of the trend of “encircling the city” with construction waste, the municipality feels a headache and the public is even more troubled. To solve the problem fundamentally, it is necessary to recycle it. Therefore, the building of waste has become an urgent need.
At the same time as a large amount of construction waste in Nanjing, Nanjing Nantong Meitong Recycling Resources Co., Ltd. aims at the “special resources” of large-scale discharge of construction waste in cities in light of the comprehensive utilization of national resources, innovation of wall materials, and development of circular economy policies. The machine construction waste recycling and treatment technology and construction waste mobile crushing station equipment have successfully produced lightweight composite thermal insulation blocks with superior performance and waste rejection rate of up to 85%. This new wall material scientific research achievement has also opened up a new road for energy saving and emission reduction in the wall material industry in Jiangsu Province and even the whole country, and has been widely applied throughout the country.
In 2008, after the introduction of German technology, our company upgraded the crushing and screening technology and developed a construction waste crusher. The first equipment was put into use in the demolition and relocation of Chengzhong Village, Kunming, Yunnan. Since then, they have entered the markets of Shenzhen, Guangzhou, Zhengzhou, Kaifeng, Luoyang, Nanjing, Nantong, Taizhou, Hangzhou, Yongkang, Haining, Jilin, Wuhan, Changsha and Xiamen, and have found a good outlet for domestic construction waste. The entire construction waste is a treasure. After effective development, the utilization rate of construction waste in China can reach more than 95%.
After the construction waste is initially cleared, the recyclable timber is sorted out, then the masonry and cement concrete blocks are broken into aggregates, sieved to remove impurities, and the raw materials for building materials with certain particle size requirements are formed. Reuse of construction waste bricks can turn construction waste into environmentally friendly bricks. After testing, the new building materials produced are superior to other building materials in terms of quality, hardness, etc. The entire production process does not produce any harmful gas, and basically realizes zero discharge of local construction waste. At present, China’s construction waste recycling and utilization areas are becoming more and more extensive. China’s construction waste recycling brick manufacturing technology has reached a certain level and has been practically applied.
